If you prefer to be elegant but keep it subtle then this is an excellent nail art that you need to try on. I did the very same thing inside this nail art and receive an incredible result.
Diva's nails: Nails with lilac pink enamel.
The nails are painted with royal blue and blue gray polish as base colors. Atop the blue gray nails rests pretty butterflies in light blue polish with black polka dots surrounding them. The nails are also painted in royal blue sparkles for effect.
